>It even works today, and there are no known attacks against AES that can reduce the work enough to beat the heat death of the universe. Well, that's the problem isn't it? The known attacks aren't the ones you have to worry about. Nearly every form of cryptography to date was expected to last longer than it actually did. I would not be at all surprised to find AES-256 broken before I'm on the wrong side of the grass.
